JOHN M. HANSEN, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR'TO PRESSED STEEL CAR COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPORATION OF NEW JERSEY;

BODY-BOLSTER FOR RAILWAY-CARS.-

SPEGIFIGATION formingpart of Letters Patent No; 749,133, dated January 5, 1904.

Original application filed December 21, 1900, Serial No. 40,649. Divided and this application filed August 28, 1901. Serial To allwhom it may concern:

Beit known that I, JOHN M. HANSEN, a citizen of the'United States, residing at Pittsburg, in'the county of Allegheny and State of Pennsylvania, haveinventedacertain new and useful Improvement in Body-Bolsters for Railway-Cars, of which the following is a full, clear, and exact description.

This invention relates to bolsters built in with and as a part of the underframe of railway-cars, and more especially freight-cars, and particularly cars for conveying ballast and the like, the last being commonly known as center-dump ballast-cars, and this case [5 is a division of my application for patent for center-dump ballast-cars, filed December 21, 1900, Serial No. 40,649.

The object of the invention is to construct abody-bolster within and asa part of the un- 'derframe, especially of metallic center-dump ballast-cars, the parts being preferably of plate-steel orsheet-steel pressed to shape and assembledby riveting, although other material than pressed steel may be used.

The in vention consists of a bolster comprising a pair of parallel channeled beams extending continuously between and secured to the side sills and havinga cover-plate extending from side to side of the car and from the inner edge of the bolster outwardly toward the end of the car and of greatest width in the plane of the draft-rigging, and a correspondingly-shaped cover-plate applied to the lower edge of the bolster and extending from side bearing to side bearing and also projecting outwardly toward the end of the car and of greatest width in the plane of the draftrigging, all as I will proceed now more particularly to set forth and finally claim. I

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view of the underframe with the body omitted from the left-hand end. Fig.

2 is a plan view similar to the left-handend of Fig. 1 and on a larger scale and illustrating another arrangement. Fig. 3 is a longitudinal section taken substantially in the plane of line A B of Fig. 2.

(No model.) 1

Fig. 4 is a halfsection and elevation of the bolster in posivtion in the underfralne.

The trucks, the couplers, and the air-brake mechanismillustrated in part-in Figs. 1 and 2 may be of any approved construction, and therefore need no detailed description in this specification. The un derframe comprises side sills 2 and end sills 3 and draft-rigging sills 4, also of approved construction.

The body-bolsters are of box-girder type, and the novelty in their construction is as follows: Between the side sills are arranged the transverse channeled beams 5, which constitute the foundation of the body-bolster, and these beams 5 are covered in at top by a plate 6, which is riveted to the upper flanges of the beams 5 and is of greatest width in the planeof the draft-rigging sills 4 4, the same being also riveted to the flanges of these sills 4 4 and to the flanges of the side sills 2. Also at the top are applied gusset-plates 7, of tri- 7o angular outline, and which are riveted to the upper flanges of the inner beam 5 and the upper flanges of the side sills. The ends of the beams 5 are dished at 8 to provide clearance for the wheels, and next to these dished portions are secured the side bearings 9. Between the side bearings and underlying themis the bottom cover-plate 10, of the outline shown by dotted lines, Figs. 1 and 2, and, like the plate 6, extending outwardly and having its greatest width in the plane of the draftrigging sills. By this construction of top and bottom cover-plates and gussets the under frame, including the bolster, is greatly reinforced to resist the shocks and strains imposed upon this portion of the car.

As shown in Fig. 2, the underframe may be further strengthened by the use of oblique braces 11, which diverge from the bolster at the draft rigging sills toward the angles formed by the junction of the side and end sills, and these junctions may be further reinforced by gusset-plates 12, or, as shown in Fig. 2, these braces (designated 13 in that figure) may diverge from the draft-rigging sills at the end sill inwardly toward the junction of the bolster with the side sills, and suitable gusset-plates 14 may be arranged in the angles between the draft-rigging sills and the end sills. In either case the oblique braces will be riveted to the top cover-plate and the gusset-plates.

As shown by reference to Figs. 1 and 2, the center sills 15 are out of longitudinal alinement with the draft-rigging sills. These center sills are preferably composed of angle steel or iron, rolled or wrought, and their ends are bolted or riveted to brackets 16, which in to rn are secured to the beams forming the bolsters. These center sills are arranged at an incline corresponding to the incline of the bottom of the body,as shown more particularly in Fig. 4.

The underframe thus describedis designed, as already intimated, especially for a centerdump ballast-car body, and in that case the said body is mounted immediately upon the center sills, and in order to distribute the load and pressure to the side sills also there may be interposed between the said side sills and the body or center sills the transom 25 in any of a variety of ways, (see, for examples, Figs. 1 and 4,) and the braces 26 may project from these transoms to the inverted apexial end of the body, as indicated in Fig. 4.

Plate or sheet metal or other equivalent metal of suflicient strength and stiffness and pressed to shape may be used in the construction of most or all of the parts herein shown and described, although the center sills may be rolled and the various brackets and bearings may be castings.

By the construction of underframe herein described I obtain great strength and stifiness and also great load-sustaining capacity with facility of repair.

While the underframe herein shown and described is designed especially for dumpballast cars, I do not limit its use to that one character of car.

The features of the herein-described and shown underframe not herein specifically claimed are reserved for my application for patent filed August 21,1901, Serial No. 72,832, which also is a division of my application, Serial No. 40,649, herein before referred to, and other features herein in part or otherwise shown and described are reserved to the aforesaid original patent application and any other division thereof wherein they are claimed.

What I claim is v 1. The combination of side sills and bolsters, each bolster comprising a pair of parallel channeled beams extending continuously between and secured to the side sills, with a bolster cover-plate extending from side to side of the car and from the inner edge of the bolster outwardly toward the end of the car and of greatest width in the plane of the draft-rigging, and a correspondinglyshaped cover-plate applied to the lower side of the bolster and extending from side bearing to side bearing and also projecting outwardly toward the end of the car and of greatest widthin the plane ofthe draft-rigging,substantially as described.

2. The combination of side sills,continuous transverse bolsters extending from side sill to side sill and secured to said side sills,coverplates for said bolsters applied above and below them and of greatest width in the plane of the drafterigging, end sills, and oblique braces interposed between the end sills and the said bolsters, substantially as described.

3. A bolster for under-frames, composed of continuous parallel channeled beams of a length to extend between and be secured to the side sills of the car,a top cover plate riveted to the upper flanges of the beams and of greatest width in the plane of the draftrigging,substantially triangulargusset-plates riveted to the flanges of the inner beam, and a bottom cover-plate also of greatest width in the plane of the draft-rigging,substantially as described.

4. A body-bolster, of box-girder type, composed of parallel channeled beams of length sufficient to extend continuously from side sill to side sill, and top and bottom coverplates, and having its lower portion dished at opposite ends to provide clearance for the truck-wheels, substantially as described.

In testimony whereof I have hereunto set my hand this 16th day of August, A. D. 1901.

JOHN M. HANSEN.
